Normal Operation
When the headlamp switch is placed in the HEADLAMPS ON position, the central junction box (CJB) routes the voltage to the low beam headlamps through circuits 160 (DB/WH) (LH low beam) and 161 (DG/OG) (RH low beam). The headlamps are individually grounded through circuit 57 (BK).

Possible Causes
- Fuse
- Circuit 57 (BK) open
- Circuit 160 (DB/WH) open
- Circuit 161 (DG/OG) open
- CJB
